To make any good cocktail it is essential to have a balance of each element (within the cocktail) poured correctly. Therefore the accuracy with which the ingredients are measured is critical to the flavour of the finished cocktail. In most of my cocktail recipes, I have explained to use a single ”shot’ (25ml) or sometimes a double ‘shot’ (50ml).
You can either use a ‘shot’ glass to help you measure correctly or alternatively you could use a plastic medicine measure, (if you do not have the proper stainless steel measure available). Some cocktail barmen measure shots by counting time and estimating the amount of fluid flowing through the bottle’s spout. This is known as ‘free pouring’ and can be accurate in skilled hands. Hope this information is useful to you.
